These special attributes determine that vocational education is irreplaceable for other types of education. The remarkable characteristics of vocational education are embodied in three aspects: locality and industry, skill and market orientation. The starting point and end result of developing vocational education in local and industrial sectors are mainly to serve local economic construction, social development and industrial development, and to serve people's employment. Mr. Huang Yanpei once said that vocational education is to "make the unemployed have jobs and work happily" and "make a living for themselves and serve the community". Mr. Yan also pointed out that vocational education is mainly to cure fools, poverty, weakness and private affairs. These famous theories have clearly put forward the purpose of developing vocational education. The function of modern vocational education has been greatly broadened, but the starting point and destination are also inseparable from serving local economic and social development and industry (enterprise) production. 2. Technical skills The technical skills of vocational education are determined by the training objectives. Students trained by vocational education directly enter the labor market. Although with the establishment of lifelong education system and education overpass, vocational education will no longer be and should not be a "fault" education. Students in vocational schools can continue to advance to a higher school for further study. However, after all, the number of students is small. Therefore, only by letting students master professional technology and skilled skills can they be competent for employment, which is also the essential requirement of vocational education. 3. There are many market factors affecting vocational education, including solidarity market, capital market, resource market and labor market. The most important thing is the labor market. In a sense, the demand of the labor market plays a decisive role in the development of vocational education. The development of vocational education must consider students' full employment, which is the key to measure the success of vocational education. The labor market is constantly changing and full of vitality. First, with the development of economy and society, the scale of talent demand in the labor market is constantly changing. The second is the adjustment of industrial structure and post changes. Third, with the progress of science and technology, the technical structure of the labor market has been continuously upgraded, and the production posts have changed from low skills to high skills, which requires higher and higher quality of talents. Fourth, the mobility of talents in the labor market has increased. It is precisely because of these changes in the labor market that vocational education must fully consider these factors, so that the trained talents can meet the market demand and graduates can be fully employed. What the labor market needs and what it doesn't need should be an important basis for the development of vocational education.
